Buick Park Ave
On the 1994 Buick Park Ave, when the Blower Motor continues to run even with the ignition off, this is most commonly due to a faulty Blower Motor Control Module. You can find the module located under the hood towards the rear/passenger’s side of the engine compartment, mounted to the blower motor housing. Carefully inspect the electrical connector and harness for any loose, broken or damaged wires. If the visual inspection checks ok, replacing the blower motor control module should solve the problem.
